Some of these memory locations are special registers, while others are user files. To communicate with the PIC microcontroller one has to learn how to program it using its instruction set. The 16F84 chip has a 1k 脳 14 bit word EEPROM program memory, 68 脳 8 bit general purpose registers...
On the first instruction, we SET the Zero flag. On the next instruction, we check if the Zero flag is set. The BTFSS means Skip If Set, thus, the following instruction will NOT be executed, as the Zero flag is SET. As a matter of fact, the PIC will NOT jump the following ...

INTRODUCTION TO PIC 16F877 Data Transfer Group Instructions in PIC Data transfer group instructions are one of the major instructions widely used in PIC programming for data transfer purposes. By using these types of instructions, we can move or change the value (bits) from one location to anot...
A PIC microcontroller U4 serves both as a frequency counter, as well as the sidetone oscillator. Pressing the FREQ counter at the side of the enclosure activates the counter, which counts the VFO frequency, and sends four digits of the count (excluding the megahertz digit) as CW characters ...
